I think there is something there, it might be just my blind optimism and belief...
I think the football (early on) was encouraging, the passing and build up play was all there without that clinical striker to finish it all off. I'd also argue that he can bring in some decent players - obviously not all players have worked out here, Rooney being one. Players like Smith, Philliskirk, JCH & Harkins show that he has got an eye for a player, in some respects.
Like I said, some qualities, he's obviously not the perfect man nor will he ever be, but I think given another summer and an opportunity to partially rebuild, bin the crap and bring in some more to add to the core of the team, we could go on to have a successful (not promotion, probably) season.
It's all if's and but's - but, I think we're better off sticking rather than twisting this time. Time is the operative word in this scenario - let's see where we end up, binning managers after a year in charge can't be healthy.
Just a sidenote from me, I personally think lack of investment is our biggest problem and has been since Blitz walked out in 2009? I don't think Johnson or many other managers can perform miracles on our budget without time.
